SUPPORTING-FRAME FOR ROTARY FANS.

SPECIFICATION forming part of Letters Patent No. 488,293, dated December20, 1892.

Application tiled November 18, 1.891. Serial No. 412,341. (No model.)

To @ZZ whom t may concern:

Be it known that I, SYLvANUs D. SHEPPERD, of Newark, in the county otEssex, State 'of New Jersey, a citizen of the United States, haveinvented certain newT and useful Improvements in Supporting-Frames forRotary Fans, of which the following is a specification.

This invention relates to that class offrandes for supporting-fans thatare attached to ceilings.

The object of my invention is to provide a fan-frame of this kind, whichis simple in construction, can be packed in small space and easilyerected and fastened for use.

The invention consists in a supportingframe for rotary fans constructedwith an annular top-frame, a circular intermediateframe anda bottomsocket-piece, rods extending from the socket-piece to the annulartopframe and through the intermediate-frame, tube-sections surroundingsaid rods between the top and intermediate frames and the socket-piece,and a fan-shaft mounted in the intermediate-frame and in the bottomsocketpiece.

The invention also consists in the construction and combination of partsand details as will be fully described hereinafter and iinally pointedout in the claim. M

In the accompanying drawings, Figure l is a vertical,transversesectional view of my improved supporting-frame for rotary-fanson the line 1 l of Figs. 2 and 3; Fig. 2 is a planview of the undersideof the annular topframe and spider, parts being broken out; Fig. 3 is aplan-view of the underside of the intermediate transverse circularframe; Fig. 4 is a plan-view of the bottom socket-piece; Fig. 5 is aside-view of the same; Fig. 6 is an enlarged, vertical, transversesection of the ornamental bottom-nut.

Similar letters of reference indicate correspending parts.

The annular frame A, protiled according to any desired pattern, isprovided on its underornaniental surface with three sockets A in the topof each of which an' aperture ce is formed. Said annular frame A is alsoprovided on its inner edge adjacent to each socket a with a lug Bprovided with a nipple b on its underside, which nipples b tit intodepressions or recesses c in the ends of the arms of a spider-frame C,provided with a central aperture O, through which the screw-bolt D or ananalogous device is screwed into the ceiling or like support.Theintermediate circular-'frame E is provided at its rim with thesockets F on the underside and the socketsG on the upper side, aperturesg connecting the corresponding sockets. Arms E connect the ringshapedframe E with the hub H having alongitudiual bore through which thefanshatt J can pass. The bottom socket-piece K is provided on its upperend with the three sockets L and in its underside with the three socketsM, which sockets are connected by the apertures m, and said socket-pieceK is also provided with a central bore N for the fan-shaft J. Ornamentalnuts O, the upper ends of which t into the bottom sockets M in thesocket-piece K are screwed on the lower ends of rods R, which are passedthrough the apertures m of the socket-piece K, the aperture G of theintermediate-frame E and the apertures a ofthe top-annularfrarne A. Theupper ends of said'rods are threaded and nuts P screwed thereon, whichnuts are concealed within the cavities ot the ring-shaped piece A.Between the frames A and E the rods R are surrounded by the Vtubes S,the ends of which are held in the sockets A ofthe frame A and thesockets G of the frame E, and between the frame E and the socket-piece Kthe rods are surrounded by tubes S', the ends of which are held in thesockets F of the frame E and the upper socketsL of the socket-piece K.By drawing-up the nuts P, the several parts forming the frame can bedrawn firmly andrigidly together. The fan-shaft J is surrounded by atube T, the ends of which rest in the central top-socket of thesocket-piece K and in the socket in the lower end of the hub Il of theframe E, and on the upper end of said fan-shaft the grooved-pulley Wistired, over which the driving-belt W passes. By loosening the screw Dthe entire frame can be removed from the ceiling, and can easilyloe'taken apart upon takingoif the nuts P. The frame can thus be packedvery compactly for shipping and can easily be erected for use. It isstrong, rin and rigid, as the rods and tubes thoroughly brace cachother.'

IOO

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is In a supporting frame for rotary fans, thecombination, with an annular top-frame having sockets at its under side,of a bottom socket-piece having sockets in its upper and under sides, anintermediate circular frame also having sockets in its upper and undersides and a central sleeve forming a bearing for the fan-shaft, rodsconnecting the top frame and theI socketpiece and passing throughapertures in the intermediate frame, top-sections su rrounding said rodsand having their ends resting in the sockets of the topframe,intermediate frame and socketpiece, nuts screwed on the upper ends ofsaid rods above the upper surface of the top-piece, nuts screwed on thelower ends of said rods and resting on the upper edges of thesocket-piece, a tube extending from the annular piece to theintermediate piece, a fan-shaft having bearings in the sleeve of theintermediate piece and in the socket-piece, a pulley fixed on said shaftabove the intermediate'piece and fan-Wings secured on said shaft belowthe annular piece7 substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
